Erhard, I am not sure what you mean. I believe bulk case placement only refers to C's & R's. Even then placing only 0603 and 0805. I assume you are talking about larger parts since you mention trays???

What's the metallization on the board? We use an immersion tin board and had to increase our profile to successfully solder.

Has anyone had trouble waving and gluing 0603 R's and C's? At my company, our designers have "opened the floodgates" on bottom-side 0603's. We've got an EPK+ with rotary chip and omega wave but can't seem to get skip-free soldering on these guys.

R&D is currently designing a board with smt components on both sides of the board. They are adding a 16 pin IC Gull wing. on the bottom side of the board. I have asked for only caps and resistors to be placed on the bottom side. Is there a recommende

Yes. I have both R-L and L-R machine in house and we swap stencils betweeen them all the time. Stencil programs from R-L to a L-R machine (and vise/versa) will not.

Folks, At the moment I bake all BGA that are in unsealed trays, to reduce moisture etc. Is this common practice or are there particular manufacturuers that cause more problems. Also, the tape for BGA tape & reel has a hole in the tape (as is normal

Hi. I've been looking for SMT machines and have a budget close to 100k total on a stencil printer, p&p + feeders and reflow owen. Witch machines would you choose with this budget? Have any one of you heard of evest? http://www.evest.com.tw/product.h

Hi Jeff, no problem, I'll just pop them out and make copies. I'm betting the upgrade will take care of these silly problems. The machine with the "newer" firmware just goes and goes without any issues other than replacing that R-axis servo a while

Jeremy: Parts assembler make leads of either Alloy 42 (Invar, whatever) or copper. The solderability of these leads are protected with eutectic or non-eutectic tin/lead solder, palladium or some palladium alloy, or gold. Cuppla things to consider:
